I cant get the values in the policy editor to highlight blue. Instead I get this error. What does this mean.

alert any any any -> any any (msg:"test";content:"authenticated"; pcre;pcre:"([A-Z]{3}\s[0-9]{2})\s([0-9]{2}\:[0-9]{2}\:[0-9]{2})\s([a-z0-9]+\.[a-z0-9]+\.[a-z0-9]+\.[a-z0-9]+)\s([a-z0-9]+)"; nocase; adsid:777; sid:0; norm:0; severity:0; )

Re: Regex Support

The error is telling you that one of your regexes is not referenced in your field mapping. The UI won't allow you to save the custom rule until you've fully mapped the captured regex strings into SIEM database fields.

For troubleshooting your regex, you might like to try a tool like RegExe (http://gskinner.com/RegExr/). It provides excellent real-time feedback on your regex as you're building it. Right off the bat it appears that your first token "[A-Z]{3}" will likely fail to match the string "Nov", due to case mismatch.
